Mandatory Curtailment Option: Enrollment requires you to reduce and maintain load during each Mandatory Curtailment Period to the level specified in your PowerShare contract. Curtailment is implemented when Duke Energy experiences capacity constraints. Incentive credits are paid monthly and for load curtailed during each event.

Voluntary Curtailment Option: Participation allows you to take part in Voluntary Curtailment Periods on a per event basis. If you elect to participate in an event, you must reduce and maintain load to a level you specify prior to the event. Curtailment is initiated at Duke Energy’s discretion and notification is typically provided one business day in advance. Credits are paid for load curtailed during each event.

Generator Curtailment Option: Enrollment requires load transfer from the Duke Energy source to a private generation source during each Generator Curtailment Period. A Generator Curtailment Period is implemented when Duke Energy experiences capacity constraints. Incentive credits are paid monthly and for load transferred to the generator during events.

CallOption: Enrollment requires you to reduce and maintain a predetermined electrical load during Emergency and Economic Curtailment events. You select the number of events in which you'd like to participate on an annual basis. The CallOption provides customers with shorter contracts, longer lead times, lower load requirements, and buy-through provisions for Economic Events.

Duke Energy is committed to meeting our customers’ growing energy needs in a responsible and low-cost way. Building new generation facilities is expensive. Our demand-response programs are the cheapest, fastest and cleanest way to meet energy demand, while providing our business customers with a way to profit from their energy curtailment.
